CONNECTION NOTES 9 Avoid connecting the generator to commercial
power outlet. 9 Avoid connecting the generator in parallel with any
other generator.
1 Correct 2 Incorrect
EXTENSION CORD NOTES Extension cords should be protected by a tough flexi- ble rubber sheath (IEC 245) or the equivalent to with- stand mechanical stresses.
CONNECTION
Before the generator can be connected to a build- ings electrical system, a licensed electrician must install an isolation (transfer) switch in the build- ings main fuse box. The switch is the connection point for generator power and allows selection of generator or main line power to the building. This will prevent the generator from charging the main power line (backfeeding) when the main power supply has failed or has been turned off for line repair. Backfeeding can electrocute or injure line maintenance personnel. Also, generator and build- ing electrical system damage can occur when nor- mal operating power returns if unit is used without an isolation switch.

G.F.C.I. RECEPTACLE
TO REDUCE THE CHANCE OF ELECTRICAL SHOCK: 9 Do not attempt to operate electric devices if
the ground fault circuit interrupter reset button pops out repeatedly during use.
9 Test the ground fault circuit interrupter during the pre-operation checks according to the maintenance instructions on page 35.
9 Remember that only receptacle labeled GFCI have ground fault circuit interrupter protec- tion.
The G.F.C.I. (Ground Fault Circuit Interrupter) shuts off power to the protected receptacles if a ground fault (electrical leak) is detected. If the reset button pops out, the electric devices con- nected into the receptacle may be faulty. If this hap- pens, check the electric devices carefully. If the elec- tric devices appears to be in good condition, press the reset button firmly until a click is heard. This will restore power. If the reset button pops out again, dis- connect all the electric devices immediately. Have the electric devices inspected and repaired by a qualified repairperson before attempting to use them again.

SPARK PLUG INSPECTION The spark plug is important engine components, which should be checked periodically.
1. Remove the spark plug cap and the spark plug.
2. Check for discoloration and remove the carbon. The porcelain insulator around the center elec- trode of spark plug should be a medium-to-light tan color.
3. Check the spark plug type and gap.
a Gap
TIP The spark plug gap should be measured with a wire thickness gauge and, if necessary, adjusted to specifi- cation.
4. Install the spark plug.
TIP If a torque wrench is not available when installing a spark plug, a good estimate of the correct torque is 1/41/2 turn past finger tight. However, the spark plug should be tightened to the specified torque as soon as possible.
5. Install the spark plug cap.
CARBURETOR ADJUSTMENT The carburetor is a vital part of the engine. Adjusting should be left to a Yamaha dealer with the profession- al knowledge, specialized data, and equipment to do so properly.
Standard spark plug: BPR4ES (NGK)
Spark plug gap: 0.70.8 mm (0.0280.031 in)
Spark plug torque: 20 Nm (2.0 mkgf, 14 ftlbf)
